Wow i feel like a bozo.... I dropped script into the SD root and when I connect via wifi to the Action YI app it still switches to chinese... really frustrated..
Any ideas? Perhaps you can write a quick step by step idiot proof version of the process for people like me?

Copied autoexec.ash down.
Blanked the fieland put in script from earlier in the post
left last line blank
Saved it into root of SD card.
inserted SD card into camera
Powered up
Turned on the camera WiFi
Connected to camera
Opened App and still in Chinese.
Reinstalled app and rebooted phone and that did not change anything.
So any help would be appreciated.
